Gulp build improvements, update.

[dannon]

Support --limit in gulp's viz plugin building, to isolate particular plugins or sets for rebuilding. Also updates to the (surprisingly) new gulp 5, which drops a slew of older dependencies. WIP in another branch to just de-gulpify all this, but it's not a priority right now; I just wanted to pop this out a set of various other viz fixes I'm working on getting in.

i.e. yarn run gulp pluginsRebuild --limit nora

So the new gulp is failing on a step that has apparnetly been failing for a while now, just silently. Will update.

Thank you! This is now way faster, specially when you already have the dependencies installed but don't have internet access 👍

Hmmm, it seems lib/galaxy_test/selenium/test_visualizations.py::TestVisualizations::test_charts_h5web fails consistently in CI. I checked locally and it passes for me, I'm using node 20, so I switched to node 18 (like in CI) and the plugin doesn't load.
Now that I think of it, I vaguely remember we talked about updating the node version in one of the meetings... but I don't recall the reason, maybe it was because of this? (sorry, fish memory... 😅)

I switched back to node 20 and now it still fails locally (it cannot find index.js and index.css for the plugin), so it is not related to the node version, sorry for the noise. It might have worked because I had prebuilt visualizations from other branches.
